Abstract: A method controls access permission to an image including receiving session information from a first camera at a first position, the session information indicating a subject to be photographed and a session in which the first camera joins, receiving an image of the subject from the first camera, updating the session information such that a second camera, at a second position, joins the session, and monitoring whether the second camera joins the session. A first period is calculated in which the second camera joins the session, a second period is calculated based on the first period, and access permission to a shared image is controlled such that the second camera downloads the shared image during the second period and does not download the shared image outside of the second period, the shared image being one of the image and an image generated based on the image.

Abstract: A dimension measurement device includes a processor and memory. The processor, using the memory, obtains a three-dimensional model of a target object, selects a basic shape from a plurality of basic shapes, each of the plurality of basic shapes being a corresponding candidate of a three-dimensional shape, fits the selected basic shape to the three-dimensional model, and measures a dimension of the target object using the basic shape that has been fitted.

Abstract: A three-dimensional model generation method executed by an information processing device includes: obtaining a first three-dimensional model from a measuring device that emits an electromagnetic wave and obtains a reflected wave which is the electromagnetic wave reflected by a measurement target to thereby generate a first three-dimensional model including first position information indicating first three-dimensional positions in the measurement target; obtaining a multi-viewpoint image generated by one or more cameras shooting the measurement target from different positions; and generating a second three-dimensional model by enhancing the definition of the first three-dimensional model using the multi-viewpoint image.

Abstract: A three-dimensional displacement measuring method includes: calculating camera parameters of N cameras based on M correction images shot at M viewpoints by cameras including the N cameras, where N is an integer greater than 1 and M is an integer greater than N, the M viewpoints being mutually different; and measuring a displacement over time of a subject caused by vibration of the subject in a three-dimensional space, based on (1) sets of N images and (2) the camera parameters. The N images in each of the sets are generated by the N cameras shooting the subject at the same time, and the sets are generated at different times. The different times are set according to a frequency of the vibration of the subject.
